Description
ilO(~807 The present invention relates to a device for the trans-fer of fresh air from a stationary place to a moving receiving place such as a movable operating cabin or the likeO
It is known to supply fresh air to a moving operating cabin by means of a flexible tube that does not hinder the move-ment of the operating cabinO However, it is troublesome to sup-port and guide the fle~ible tube while the operating cabin is movedO Also, the movable flexible tube is a hindranceO The disadvantages of a flexible tube are avoided by structure shown in Canadian patent application No~ 294,575 filed January 9, 1978 in the name of Eric SvenssonO This structure however requires a vacuum to be maintained in the device.
The present invention relates to an embodiment that requires an over-pressure in the device for the transfer of substantially fresh air to a moving air exhaust placeO
The device for the transfer of substantially fresh air from a stationary place to a moving air receiving place compri-ses a stationary elongated box that has a tube or the like con-nectable to a stationary place~ In its longitudinal direction, the box has a slot that is closable by a tightening band covering the slot. The band at its ends is firmly connected with the box.
A connection body, provided with a passage for fresh air supply to the receiving place, is guided in and displaceable along the slot while it is sliding against the tightening band that is held in contact with the connection body by means of press members sup-ported by the body and acting against the tightening band.
According to the present invention the tightening band is placed inside the box, tightly bearing on the parts of the box adjacent the slot~ An over-pressure in the box acts to press the tightening band along the box parts adjacent the slot without hindering longitudinal displacement of the connection body.
The invention is illustrated by an embodiment shown on -- 1 -- /~
~lV~U8()7 the accompanying drawing as an exampleO
Fig~ 1 is a plan view of the device according to the invention and with a middle part cut away.
Figo 2 is a longitudinal section along line A-A in Fig~ 1~
Figo 3 is a cross section along the line B-B in Figo 20 Figo 4 is a cross section along the line C-C in Figo 2.
The device shown on the drawing has an elongated box 1 to the one end wall 1' of which an inlet tube 2 is connected.
The box has a rectangular cross section and the length is as neededO In one side 1" of the box 1, there is arranged a longi-tudinal slot 3. Inside the box 1 and bearing on the parts of the box bottom 1" adjacent the slot 3, is an air impenetrable tighten-ing band or tightening belt 40 The ends of the band are fastened to attachments 5 at the ends of the box.
A hollow connection body 6 extends transversely through, and is displaceably positioned in, the slot 3. The body 6 has two guiding edges 7 bearing against the inside of the box and two backing rollers 8 bearing against the outside of the parts of the box bottom adjacent the slot 3 The body also has an outlet pipe 9, rectangular in cross section, which bears against the longitudinal walls of the slot 3. That part of the connection body within the box is formed to have a convexly ar-cuate slide path 10 for guiding the tightening band 4 in the lon-gitudinal direction of the slot 30 The connection body 6 carries press members 11 at the ends of the slide path 10 in order to hold the tightening band against the slide pathO The press members 11 can be in the shape of slide shoes, made for instance of Teflon*, or in the shape of rollers. In both cases the press members can also be elastic or can be elastically supported.
That part of the hollow connection body 6 inside the box has side openings 12, which together with the cavity 6' of the .i,~, .. _ 2 *Trade Mark llOu807 connection body 6 and its outlet tube 9 form a passage in the connection body 60 The described device is used in the following wayO The box 1 is fixed along the path of movement of the enclosed space such as an operating cabin in a factory, that is to be furnished with fresh air during its movementO The inlet tube 2 is connec-ted to a pressure air source and possibly also to a heating, cooling and/or moistening aggregation filter etcO in order to obtain the desired air qualityO The outlet pipe 9 is adapted directly, or by means of an attached short extension pipe, to connect with the interior of the operating cabin. Consequently, during the cabin's movement it displaces the connection body 6 in the slot and air is continuously transferred from the box 1 to the operating cabin. During movement of the connection body, the slide path 10 lifts the tightening band 4 from the slot 3 but the remainder of the slot nevertheless is substantially closed due to band tightening by the press members 11, and also due to the over-pressure existing in the box 1 as a result of the pressurized air provided through inlet 2 The over-pressure 20 in the box may be controlled by choking of the air flow on the -outlet side.
The device according to the invention has the advantage that it does not require flexible tubes for the transfer of fresh air to the moving operating cabin. Also the device is -reliable in service and consists of relatively simple, easily manufactured parts. Further, two devices according to the inven-tion can be coupled together in a T-shape for example. In such a construction, the inlet tube of the one box is connected to the outlet tube of the other box and the outlet tube of first mentioned box is connected to an operating cabin that is movable both along and transverse over a factory room.
~<~ y The invention shall not be considered to be restricted : ' ~ ' . - .:..... ' .
~10~8~)7 to the embodiment described and shown in the drawing as this embodiment can be modified within the scope of the inventionO
For instance the cross section shape of the box and of the outlet tube can be variedO Also the members of the connection body, so as to partly be guided and retained in the slot and to partly guide the tightening band in relation to the connection body, can be modi~iedO Further the slide path of the connection body can be replaced by a number of rollers.
